Abstract: A process for producing Caro's acid by reaction of at least 85 % by weight sulfuric acid and at least 50 % by weight hydrogen peroxide wherein the sulfuric acid (9) and hydrogen peroxide (1) are fed through separate feed lines (11 and 3), respectively, into a funneling zone (17) open to the atmosphere, the feed lines (11) and (3) having air gaps between their ends and the funneling zone (17); passing the hydrogen peroxide (1) and sulfuric acid (9) by gravity flow from the funneling zone (17) into one end of a reaction zone (22) whose size permits a pressure drop which is at least 8 times the theoretical pressure drop for such reaction zone (22) and removing a mixture containing Caro's acid (28) from the exit end (26) of the reaction zone (22).
Patent CA-2201241-A1 (CA)
Title: Optogalvanic spectroscopy with phase independent detection
Inventor: LIE HANS P
IPC: G01N21/17
Filed: 1997-03-27
Abstract: In an optogalvanic spectroscopy system a plasma is exposed to light at a wavelength associated with a particular species in the analyte. The light is amplitude modulated. The amplitude of a modulated component in the signal representing electrical impedance of the plasma is detected in a phase independent manner so that the detected amplitude is substantially independent of the phase of the modulated component in the impedance signal relative to the amplitude modulation of the light. The system has reduced sensitivity to changes in the spectrum of the applied light.
Patent CA-2202631-A1 (CA)
Title: Hydantoin-enhanced halogen efficacy in pulp and paper applications
Inventor: SWEENY PHILIP GERDON
IPC: D21H21/04
Filed: 1995-10-13
Abstract: Free halogen sources (e.g., sodium hypochlorite and chlorine) added as slimicides in high organic component process streams such as pulp and paper processing are rendered more efficacious by the addition of selected N-hydrogen compounds (namely, 5,5-dimethylhydantoin, 5-ethyl-5-methylhydantoin, cyanuric acid, succinimide, urea, 4,4-dimethyl-2-oxazolidinone, and glycouril) to the process stream. The latter compounds may be added to the process stream before or after the slimicide is added or combined with the slimicide and added directly thereto. The direct use of halogenated hydantoins has also been found to provide improved efficacy relative to free halogen sources. In addition, absorbable organic halogen by-products are reduced.

Patent CA-2212791-A1 (CA)
Title: Process for reducing sterols and free fatty acids from animal fat
Inventor: SIKORSKI CHRIS
IPC: C11B3/02
Filed: 1996-02-20
Abstract: The process for reducing sterols and free fatty acids from animal fat entails forming an oil-in-water emulsion using a mixing device such as a pump or an inline mixer; and then pumping the emulsion through a conduit for a period of time. The emulsion is made from water, liquefied animal fat and cyclodextrin.  The mixing device forms the emulsion in less than one minute; and the emulsion is pumped through the conduit for 5 to 60 minutes. During the time that the emulsion is moving through the conduit, the sterols and free fatty acids move from the fat phase to the water phase and form complexes with the cyclodextrin. These complexes are fairly stable and can be separated from the emulsion by centrifugation. The resulting fat has a reduced sterol and free fatty acid content.
Patent CA-2213449-A1 (CA)
Inventor: GRANT TERRY M
IPC: D04H1/54
Filed: 1996-03-04
Abstract: Une bande de fibres est liée par un milieu de liaison ayant été activé par solubilisation partielle avec un solvant à cet effet. Les fibres sont insolubles dans le milieu de liaison. Le milieu de liaison est partiellement solubilisé, il devient collant et peut couler pour venir en contact avec les fibres et avec lui-même. Ensuite, le solvant est absorbé par le milieu de liaison, ce qui permet au milieu de liaison de se solidifier à nouveau et de lier les fibres pour former une matrice, augmentant la solidité de la bande.

Patent CA-2218784-A1 (CA)
Inventor: ISHIGAMI OSAMU
IPC: C25D7/04
Filed: 1997-10-20
Abstract: A composite plating apparatus includes a cylindrical electrode which is positioned in a hollow section of a workpiece with a surrounding gap left therebetween. A plurality of through-holes are formed across the thickness of an outer wall of the cylindrical electrode. Composite plating liquid is jetted out through the through-holes and impinge on the inner surface of the hollow section to thereby produce turbulence. The turbulent liquid provides a uniform distribution of ceramic particles in the liquid. As a result, the ceramic particles can be co-deposited uniformly in a metallic matrix, and hence a uniform abrasion-resistant characteristic is obtained all over a resultant composite plating film.

Title: Apparatus for sorting substrate components according to size, and method of sorting substrate components therewith
Inventor: NOEL JOHN RICHARD
IPC: D04H1/40
Filed: 1996-08-06
Abstract: A forming station (9) used to make a substrate. The forming station (9) has a forming chamber (40) which deposits particles (10) and fibers (11) from an air carrier onto a forming screen movable relative to the forming chamber (40).  Inside the forming chamber (40) is at least one baffle (42), which creates a velocity gradient and low pressure zone for the air carrier. Different sized components of the substrate have different momentums, and thus are differently affected by the velocity gradient and low pressure zone. This difference causes the different sized components to be sorted according to size. The sorted components are then distributed according to size within the substrate.

Patent CA-2240907-A1 (CA)
Inventor: SMOOT LANNY STARKES
IPC: G09F9/35
Filed: 1996-12-17
Abstract: Disclosed is a virtual display (300) which provides a wide field-of-view that is lightweight and may be as thin as ordinary eyeglasses. One version of the invention includes a display (302), such as an LCD, a microlens array (304), and an aperture array (306) disposed between the LCD and the microlens array.  The virtual display provides a pin-point of light for each pixel (306) of a display (302). Each pin-point of light in collaboration with an associated microlens (308) generates a directed ray of light. The ensemble of these rays forms a coherent image on a viewer's retina. Using high "f" number microlenses permits a very short focal length between the pin-points and the microlenses and thus provides a very thin virtual display. The aperture array may be provided by a plate disposed between the display and the lens, or it may be apertures configured on the back side (away from the viewer) of the microlenses or on the front (towards the viewer) of the display. Each aperture in the array receives light from one pixel and directs a pin-point of that light to a microlens in the microlens array. Each microlens receives a single pin-point and directs the resulting ray so that a coherent image is formed on the viewer's retina.
